What is the probability of color blindness if the father is color blind and the mother carries the trait?

All daughters are normal, half the sons are color blind.
The above answer is incorrect. Half of the daughters are color blind and half of the sons are color blind. Since the father always donates color blindness, it is up to the mother in each case (in the son's case, the father is irrelevant) to determine if the child is color blind or not. Since she is a carrier, the chance is 50-50.

A mother has one allele for color blindness and one allele for normal vision. What is the probability that her gamete will have the allele for color blindnessg?

Why do you think humans have two sets of 23 chromosomes?
Bcoz one chromosome comes from mother which is always X chromosome carries characteristics from mother and the second chromosome comes from father that may be X or Y, which carries characters from father.
Is the mitochondrial DNA in a baby more like the mitochondrial DNA from his mother's mother or the mitochondrial DNA from his father's mother?
It is exactly like the mothers (except for some possible random mutations). The mother's egg has all of the cytoplasmic components inside it. The sperm only carries DNA. So mitochondria are maternally inherited. While the sperm does contain mitochondria in its tail, only the DNA from the head are transported into the ovum. The DNA of the child consists of half the genetics of the mother and half the genetics of the father. This is because the sperm carries 22 chromosomes and an extra sex chromosome (X or Y). The egg inside the mother also carries 22 chromosomes and a sex chromosome (X or X). When these meet we get 22 sets of chromosomes and a set of sex chromosome (X,Y or X,X) which determines the gender of the child. However, if the mother or the father is carrying an extra 21st chromosome and for example, the child receives 2 21st chromosomes from the father and 1 from the mother, they now have 3 21st chromosomes which can lead to the child being born with downs syndrome.
Is color blindness a sex linked disease?
Yes. A person is color blind if all his or her X chromosomes have the defective gene. A man have one X chromosome, and a woman has two. Thus: If only the father is color blind - The probability that the son is color blind is 0% - The probability that the daughter is color blind is 0% - The probability that the daughter is a bearer of the defective gene is 100% If the mother is a bearer of the defective gene, but is not color blind, and the father is not color blind - The probability that the son is color blind is 50% - The probability that the daughter is color blind is 0% - The probability that the daughter is a bearer of the defective gene is 50% If the mother is a bearer of the defective gene but not color blind, and the father is color blind - The probability that the son is color blind is 50% - The probability that the daughter is color blind is 50% - The probability that the daughter is a bearer of the defective gene is 100% If the mother is color blind and the father is not - The probability that the son is color blind is 100% - The probability that the daughter is color blind is 0% - The probability that the daughter is a bearer of the defective gene is 100% If both parents are color blind - The probability that the child, regardless of gender, is color blind is 100%
What is sex linked disorder?
it means that you inherit this form of disorder either from your mother or father's sex chromosomes. For example- color blindness or Haemophillia.
A mother has one allele for color blindness and one Allele or normal vision what is the probability that her Gamete Will have the Allele for the color blindness?

Why is it impossible for a father to pass down red green color blindness to his son?
Boys have one X and one Y chromosome. Color blindness is found on the X chromosomes. Since boys will always get their X chromosome from their mother and their Y chromosome from their father, father's can never pass on red/green color blindness to their son's. However, since father's do pass their X chromosome to their daughters, they can pass on the trait to their daughters. In this case, daughters have two X chromosomes (one from their mother and one from their father), so they will NOT have red/green color blindness unless they received the defective gene from their mother AND their father. This is the reason that color blindness is 9 times more common in boys than girls.
A color blind son inherited this trait from?
his mother because color blindness is a sex-linked trait that is found on the X chromosome, which is inherited from the mother, as opposed to the Y chromosome, which is inherited from the father. So a male can only inherit the gene for color blindness from his mom.

What will be the child's blood group if mother is A plus and Father A plus?
A positive with highest probability
What is the probability of getting curly hair?
The probability of getting curly hair depends on whether your parents do or not. Hair genes are decided by the mother. So, if the mother has curly hair, more than likely the offspring will as well. If the father has curly hair and the mother does not, the probability is considerably lowered.
Probability of son blood group being B if mother is A and father is AB?
25% to be B.
Do penguins hatched from eggs?
Yes. Another interesting fact is that the father carries the egg, not the mother.
Who is past qb for pats whose father was blind?
Former Patriots starting quarterback Jim Plunkett's father was afflicted with progressive blindness. In addition Plunkett's mother was blind as well.
Can a baby be born with B- blood if mother is O plus and father is B plus?
The mothers genotype is either OO++ or OO+-. If it is the former, then the child cannot be B-, so the mother has to be OO+-. The father is able to be either BB++, BB+-, BO++, or BO+-. If he is BB++ or BO++, then he cannot father a child to be B- by a OO+- mother. If he is either BB+- or BO+-, then it is entirely possible for he and an OO+- mother to have a child with phenotype B-. If the father is BB+- the probability is 25%. If he is BO+-, then the probability is 6.25%.
A mother has one allele for color blindness and one allele for nomal vision what is the probability that her gamete will have the allele for color blindness?
Color Blindness is x-linked recessive. Therefore, it could not be heterozygous; the daughter would not be colorblind, but rather have normal vision.
Will a boy who's father is color blind inherite the gene?
If gene related to color blindness is dominant one compared to other genes of father or mother, then the boy inherit the gene (character).
